I'm using Google Chrome 31.0.1650.63 on Ubuntu 13.04 (raring). It was all working fine but since last day whenever I restart my computer, I'm automatically logged off all the sites (such as Stack Exchange sites, Facebook, Google etc.).
I followed the steps given on this answer to enable logging on Google Chrome, but I couldn't find anything suspicious in the logs.
I've checked the Content Settings in Google Chrome, and it is set to "Allow local data to be set (recommended)".
Any ideas why this is happening?
